The EGR cooler reduces exhaust gas temperature before recirculation into the engine, improving emissions and engine efficiency. However, EGR coolers are prone to internal blockage from carbon accumulation and can develop coolant leaks that cause serious engine problems. At Metre Per Second, we provide complete EGR cooler services including diagnosis, cleaning, repair, and replacement. Our experience includes all types of EGR coolers from simple single-pass designs to complex multi-pass coolers used in modern diesel engines. We understand the critical importance of proper EGR cooler function for engine health and can advise on the best approach - whether cleaning, repair, or replacement - based on your cooler's condition.

EGR System — Your Questions Answered
Updated 2026-10-20 with fresh answers from our specialists.
What should I do if I suspect my diesel vehicle has an EGR cooler leak while driving in KPHB?
If you suspect an EGR cooler leak, first monitor for symptoms like reduced engine performance or visible exhaust smoke. Use an OBD-II scanner to check for fault codes, such as P0401 or P0402, which indicate EGR flow issues. It's advisable to bring your vehicle to a specialist like Metre Per Second for a thorough diagnostic, as our technicians employ OEM tools to precisely identify the problem and recommend necessary repairs or replacements.
What are the most reliable OEM tools for diagnosing EGR cooler issues in diesel vehicles, and where can I access them in KPHB?
For diagnosing EGR cooler issues in diesel vehicles, tools like the Bosch KTS 540 or the Launch X431 are highly reliable. These tools can read OBD-II codes such as P0401 and P0403, which indicate EGR system malfunctions. In KPHB, you can find automotive parts suppliers like AutoZone or local workshops that may have these diagnostic tools available for use.
Are there any specific driving conditions in Hyderabad that can lead to EGR cooler failure in diesel vehicles?
Yes, driving in Hyderabad's congested traffic and frequent stop-and-go conditions can lead to higher exhaust temperatures, which may accelerate wear and tear on the EGR cooler. Additionally, the presence of pollution can contribute to the buildup of carbon deposits, necessitating more frequent EGR cooler cleaning and maintenance. It's advisable for diesel vehicle owners in KPHB to consider regular inspections, especially if they notice any signs of reduced engine performance or increased emissions.
What brand-specific EGR cooler issues should I anticipate for my Maruti Suzuki diesel vehicle in Hyderabad?
For Maruti Suzuki diesel vehicles, EGR coolers can commonly experience failures due to clogging from carbon buildup or leaks caused by wear and tear. Specific models, such as the Maruti Brezza or Swift DDIS, may show OBD codes like P0401 or P0404 indicating EGR issues. It’s advisable to use OEM tools and parts from authorized suppliers in Hyderabad, like R.M. Auto Parts in KPHB, to ensure proper fit and function during EGR cooler repair or replacement.
What are the common causes of EGR cooler leaks in diesel engines, and how can I diagnose them?
Common causes of EGR cooler leaks include corrosion due to high exhaust temperatures and vibrations from engine operation, particularly in high-performance diesel engines like those from Tata or Mahindra. To diagnose, we check for OBD codes such as P0401 or P0403 and perform a pressure test using OEM tools like the Snap-on Solus. In KPHB, regular inspections can help catch these issues early, particularly in vehicles driven in congested traffic conditions.
How long does an EGR cooler repair usually take in your workshop?
On average, an EGR cooler repair or replacement can take between 3 to 5 hours, depending on the complexity of the job and the specific vehicle model. For example, larger diesel engines may require additional time for proper access. Scheduling an appointment can help us expedite the process.
Can I clean my EGR cooler myself, or should I rely on professional cleaning services?
While it's possible to clean an EGR cooler yourself using specialized cleaning solutions, professional services are recommended for thorough cleaning. We use OEM-approved tools and techniques to ensure all carbon deposits are effectively removed, restoring optimal function, especially in high-traffic areas like KPHB.
How much should I budget for EGR cooler replacement in Hyderabad?
The cost for EGR cooler replacement can vary widely, typically ranging from INR 8,000 to INR 20,000, depending on your vehicle's make and model. Brands like Mahindra and Tata may have different pricing due to OEM parts availability. Always check with local suppliers in Hyderabad for specific quotes.
What symptoms indicate that my EGR cooler might need repair in my diesel vehicle?
Common symptoms of a failing EGR cooler include noticeable coolant loss, white smoke from the exhaust, and poor engine performance. You may also experience an illuminated check engine light, often linked to OBD codes like P0401 or P0420, indicating EGR flow issues. If you're in KPHB, consider visiting us for a thorough diagnosis.

I had a great experience at Metre Per Second for my Toyota Urban Cruiser Hyryder's disc turning service. I visited their LB Nagar workshop as I was facing some brake shudder and noise, which was quite concerning. They diagnosed the issue promptly and informed me that the brake discs needed turning to fix the problem. The service was completed within a couple of hours, and the cost was only ₹4,500, which is much better than the ₹9,000 estimate from the Toyota dealership. The staff was friendly, and the job was done well. I would highly recommend them and plan to return for future services, though a slight delay in getting the car back was noted. Overall, a very positive experience!
I recently took my Maruti Suzuki Ignis to Metre Per Second for a full body denting service, and I must say, I am thoroughly impressed. After a minor mishap caused several dents and scratches on my car, I was quite concerned about the repair costs. The team quickly diagnosed the problem, explaining how they would restore the body without affecting the original paint. They quoted me ₹7,500, which was about half of what I’d been told at the authorized service center. They completed the work in just two days, and I couldn’t find a trace of the previous damage. The workmanship was top-notch, and it felt like driving a brand new car again. I will definitely recommend their services to my friends in Nagole.
I had an exceptional experience at this workshop when I took my Aston Martin DBX for a heating coil replacement. The heating system had been acting up, and after a detailed inspection, they quickly diagnosed a faulty heating coil. They explained the issue in a way that was easy to understand and provided a transparent quote of ₹27,000 for the replacement. Compared to authorized dealers’ quotes of about ₹35,000, this was a steal. The entire process took just one day, and I was pleasantly surprised by how efficiently they worked. Now, my car's heating system is functioning perfectly, and it feels like a new ride! I would highly recommend this workshop to anyone looking for quality service in Begumpet. I'll definitely return for any future needs.
I recently had my Toyota Innova Hycross painted on the roof, and I am quite disappointed with the outcome. I was charged a hefty ₹15,000 for the job, which was far more than I expected, considering I had only intended to touch up a few scratches. When I picked up the car, the paint seemed uneven, and there were some areas that didn’t even look like they were painted at all. To add to the frustration, I noticed a new rattle coming from the back that wasn’t there before. I tried to reach out for clarification, but the response was slow, leading to even more dissatisfaction. At this point, I’m hesitant to return for any future services as the quality was simply not up to standard.
I took my Volvo S90 for front brake discs replacement after hearing some grinding noises. Initially, the service was prompt, and they quoted me ₹25,000, which I thought was reasonable. However, upon picking up the car, I noticed a slight rattle that wasn’t there before the service. When I brought it up, the response was less than satisfactory, and they didn’t seem eager to help resolve the issue. After a couple of calls, they agreed to check it again, but I had to wait over a week for an appointment. The final bill came higher than expected as well, nearly 20% more than quoted. Overall, I was left feeling disappointed and unsure if I would return for any further work. This experience in Begumpet did not meet my expectations.
I recently took my Aston Martin DB9 to get the brake fluid replaced and was quite impressed with the level of service at this workshop. The fluid change was necessary as I had been noticing a slight sponginess in the brake pedal. They diagnosed it quickly and assured me that it was a standard procedure. The replacement was done efficiently, and they used high-quality brake fluid that felt much better compared to what I had with the dealer. The only downside was a slight delay in completing the service, which stretched the total time to nearly three hours. They kept me updated, but I had to ask a couple of times for the status. Overall, the cost of ₹5,000 was much more reasonable than the dealer's ₹8,000 quote, so I still walked away satisfied. I would definitely recommend them and would return for future services.
